Description

[Detailed Description of the Invention] The present invention relates to a conical-cylindrical road sign placed around a construction area during road construction, electrical work, etc.

The conical road signs shown above are usually made of red synthetic resin and have been widely used in the past.
As shown in the figure, a step portion 2 and a square base plate 3 are integrally formed at the lower end of a hollow conical cylinder 1.

However, in this case, even if the thickness of the stepped portion 2 and the base plate 3 are thicker than that of the conical tube 1 as shown in the figure, the center of gravity is still high and there is a risk that it will fall over and lose its function as a sign if it is exposed to strong winds. Instead, if they are fitted and stacked during transportation or storage, the inner circumferential wall of the upper conical tube 1a will come into close contact with the outer circumferential wall of the lower conical tube 1, making it difficult for them to separate when they are separated individually during use. However, the problem is that the work requires a lot of effort and time.

The present invention was made with the purpose of providing a conical tube-shaped road sign made of synthetic resin that does not have the above-mentioned drawbacks.
The structure includes a hollow conical tube or a hollow conical tube with a notched top, at the bottom of which there are two steps extending outward in the radial direction of the conical tube and having a height about twice the outward direction. , a square-shaped plywood continuous to the lower part of the stepped part, the stepped part and the plywood being thicker than that of the conical cylinder, and connected integrally with the lower part of the conical cylinder, and the stepped part A rib is provided on the inner surface of the conical tube, and a rib whose radially protruding end surface is continuous with the inner wall of the conical tube in substantially the same plane and whose lower surface is continuous with the lower surface of the base plate in the same plane, is provided on the inner surface of the conical tube in the radial direction. The lower surface of the upper rib is positioned in contact with the upper surface of the lower step so that a gap is formed between the upper and lower conical cylinders when the upper and lower conical cylinders are stacked and fitted. That is.

Next, an example of implementation of the present invention will be explained with reference to the drawings.

11 is a conical cylinder with a notched upper part, 12.13 is the conical cylinder 1
A stepped portion integrally formed outward at the bottom of 1, here:
A stepped upper surface 12' is formed on the lower end periphery of the conical tube 11 to protrude outward in the radial direction of the conical tube 11, and the upper surface 1
The outer circumferential edge of the conical cylinder 11 is made to hang down and a step 13 is attached in the middle to form a two-step step. , the height is at least twice the amount of outward protrusion of the upper surface 12'.

Reference numeral 14 denotes a square base plate integrally connected to the outer peripheral edge of the lower end of the stepped portion 13, and the wall thickness of the stepped portions 12, 13 and the base plate 14 is larger than that of the conical body 11. It is.

Reference numeral 15 denotes a number of ribs whose radial protruding end surface 15' is aligned with the extension of the inner wall of the conical cylinder 11 and is continuous with the inner wall, and which is provided at equal intervals radially, and each rib is connected to the conical tube 11. The tube 112 is integrally formed with the stepped portions 12, 13 and the base plate 14.

Thus, the diameter of the inscribed circle at the lower end of each rib 15 is larger than the outer diameter of the lower end of the conical tube 11, but smaller than the outer diameter of the upper surface 12' of the step 12, so that the stepped portion 12
, 13 in the radial direction and the height thereof.

Although the road sign of the present invention is constructed as described above, it is usually manufactured by molding soft vinyl chloride, and its color is usually red, but other colors may be used.

Therefore, when using the road sign of the present invention,
Although it is exactly the same as the conventional one, two steps 12 and 13 and a square base plate 14 are provided outwardly at the bottom of the conical cylinder 11, and the steps 12 and 13 and the base plate 14 are connected to the conical cylinder 11. Since the wall is made thicker and an appropriate number of ribs 15 are provided on the inner surface of the stepped portion 12 and 13, which are continuous with the inner wall of the conical tube 11, the center of gravity is lower than that of conventional road signs, making it easier to use when in use. There is no risk of it falling over easily even if it is exposed to strong winds or shocks, and when it is stacked together during transportation or storage, the rib 15a of the upper label will fall over the upper step 12 of the lower label. As a result, as shown in FIG. 4, a gap m is created between the lower conical cylinder 11 and the upper conical cylinder 11a, and there is no fear that the two cylinders 11, 11a will come into close contact with each other. The detachment work can be facilitated, and furthermore,
The stepped portions 12 and 13 formed in two stages at the bottom of the conical tube 11 also exhibit the design effect of giving a sense of beauty to the viewer.

Further, as described above, if the road sign of the present invention is molded from a soft resin such as soft vinyl chloride, there is almost no risk of damage due to impact.

Since the present invention is as described above, it is suitable as a road sign placed around a construction area during road construction, electrical construction, etc.
